This document provides a summary of a material balance study and steam and condensate system study conducted at JK Paper Ltd.'s Central Pulp Mills unit. It includes an acknowledgements section thanking various managers and staff for their assistance during the author's training period. Graphs and calculations are presented to show the material balance from the stock to the pope reel of paper machine 2, as well as the steam and condensate system of that paper machine, which is divided into 6 parts in a cascade system. Conclusions recognize the graphical representations provided and state that the material balance and flows will change according to different operating data.

Whole material balance calculation based on J.k CPM data.
This calculation change accoroding to different –different data .
All part balance show in this calculation.
And all cy and some of the flowrate and Efficiency of cleaner and screen
And loss all are mention in its desire part
This material balnce change accoroding to different –different data
Which I mention above .
Whole material balnce done by my best knowledge and guidence of my mentor

47. STEAM AND CONDENSATE SYSTEM OF PM-2
INTRODUCTION
Paper dryer or cylinder are the most popular method of drying a sheet of paper. In the
drying process steam is introduced inside the paper dryer at varying pressures depending on the
type of paper being manufactured.Steam condenses inside the drying cylinder and gives up its
latent heat.The condensate layer,non-condensibles,scales inside dryer shell,dryer surface
contamination,dryer shell,air film,paper and water vapour all offer resistance to heat
transfer.Improvement in dryin will be possible by quickly removing the condensate,keeping it in an
agitated state ,removing non condensables , evacuating dryer pocket humidity,keeping proper felt
tension.
In practice a typical sheet with 55-65% moisture enters the dryer and leaves with a
moisture content of 3-7%.Taking an average inlet and outlet moisture content of 65% and 5%.7.769
t/hr water has to be removed for production of 4.5t/hr .Thus sufficient heat is to be supplied to
evaporate this water together with supply of sufficient air to carry away the water vapour produced.
